【Abstract】 n the basis of analysing the geologycal features of Xikeng Silver deposit,the ore-forming origin is dealt with herein.The emphasis is focused on the study of the stable isotopesof hydrogen,oxygen,sulphur and lead. It is considered that the minerognetic elements stem mainly from.the edments,and the evolutionary precipitated water is the principle minerogenetic byderothrmal fluid.Magmatism becomes the significant power of heating and driving the atomo spheric precipitation.The mineralization style of Xikeng deposit is that of hydrothermal leaching.更多还原
